Product details
Overview
The MAX4544EUT+TG035 from Maxim Integrated is a single-pole/double-throw (SPDT) analog switch IC designed for precision signal routing in low-voltage, single-supply systems. It operates from +2.7V to +12V, delivers 60Ω max on-resistance (RON), 5pC max charge injection, and guarantees break-before-make switching - enabling reliable channel isolation in audio, test, and portable instrumentation applications.
For engineers reviewing the MAX4544EUT+TG035 datasheet, MAX4544EUT+TG035 pinout, MAX4544EUT+TG035 application, or MAX4544EUT+TG035 equivalent, key selection criteria include SPDT topology with guaranteed break-before-make timing, SOT23-6 package compatibility, RON flatness ≤6Ω, leakage <10nA at +85°C, and TTL/CMOS logic compatibility across supply voltages.
Technical Context
The MAX4544EUT+TG035 implements a CMOS transmission-gate architecture optimized for bidirectional analog signal switching with rail-to-rail voltage handling (GND to V+). Its internal control logic ensures break-before-make operation with tD ≤10ns (typ) to prevent momentary shorting between NC and NO paths during state transitions.
It features integrated ESD protection (>2000V per Method 3015.7), low dynamic power consumption (<5µW), and matched channel performance validated over -40°C to +85°C. The device supports analog signals up to the full supply rail without clamping diodes activating under normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
SOT23-6 package (6-pin, surface-mount, exposed pad optional per variant; MAX4544EUT+TG035 uses standard SOT23-6 without EP).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO) | Normally Open switch terminal | Connects to COM when IN = high; open-circuit otherwise - used for active signal path selection |
| 2 (COM) | Common analog terminal | Bidirectional I/O node - routes signal between NO and NC based on logic input state |
| 3 (NC) | Normally Closed switch terminal | Connects to COM when IN = low; open-circuit otherwise - provides default signal path |
| 4 (GND) | Ground reference | Return path for logic inputs and substrate bias - must be low-impedance for noise immunity |
| 5 (V+) | Positive supply input | Powers analog and digital sections; sets analog signal range (GND to V+) |
| 6 (IN) | Digital control input | TTL/CMOS-compatible logic input; high = connect COM to NO, low = connect COM to NC |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make guarantee | Ensures no overlap between NC and NO conduction - prevents signal shorting in critical routing |
| RON flatness ≤6Ω | Maintains consistent gain/attenuation across full analog signal range (0V to V+) |
| RON matching ≤2Ω | Enables precise differential or ratiometric measurements when using multiple switches |
| 5pC max charge injection | Minimizes settling error in sampling circuits - avoids post-switching correction overhead |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4543EKA-T | 8-pin SOT23-8 dual SPST with one NO/one NC; requires external logic for SPDT function | Higher pin count, less compact layout; suitable when dual independent switches needed | Select MAX4543EKA-T only if board layout accommodates 8-pin package and dual-channel flexibility is required |
| ADG849BRMZ-REEL7 | 6-pin SOT23-6 SPDT; 0.5Ω typical RON but rated only to +5.5V supply; no break-before-make guarantee | Better RON at 3.3V, but unsuitable for 12V industrial or military radios where MAX4544EUT+TG035 operates | Choose ADG849BRMZ-REEL7 only for low-voltage (≤5.5V), ultra-low-RON applications where break-before-make is not safety-critical |
Compared with MAX4543EKA-T and ADG849BRMZ-REEL7, the MAX4544EUT+TG035 uniquely combines SOT23-6 footprint, guaranteed break-before-make, and full 2.7V–12V operation - making it the only drop-in solution for ruggedized, wide-supply SPDT routing in portable test gear and military comms.

FAQ
What is the maximum supply voltage rating for the MAX4544EUT+TG035?
The MAX4544EUT+TG035 has an absolute maximum supply voltage (V+) of +13V, with recommended operating range from +2.7V to +12V. Operation beyond +13V risks permanent damage per Absolute Maximum Ratings. At +12V, RON remains ≤60Ω and tON/tOFF stay within spec - confirming suitability for 12V industrial and military radio applications.
Does the MAX4544EUT+TG035 support rail-to-rail analog signal switching?
Yes, the MAX4544EUT+TG035 supports analog signals from GND to V+ without clipping or distortion, verified across its full operating temperature range (-40°C to +85°C). This rail-to-rail capability is enabled by its CMOS transmission-gate design and absence of internal clamping diodes under normal bias conditions - critical for preserving signal integrity in audio and sensor interfaces.
Is break-before-make timing guaranteed for the MAX4544EUT+TG035?
Yes, break-before-make is guaranteed for the MAX4544EUT+TG035, with a maximum break-before-make delay (tD) of 10ns at +25°C and ≤30ns over -40°C to +85°C. This specification prevents momentary shorting between NC and NO paths during switching - a key requirement for avoiding signal corruption in multiplexed data acquisition and communication systems using the MAX4544EUT+TG035.
What is the thermal performance of the MAX4544EUT+TG035 in SOT23-6 package?
The MAX4544EUT+TG035 in SOT23-6 has a power dissipation limit of 571mW at +70°C, derating by 7.1mW/°C above that temperature. At +85°C ambient, maximum continuous power is 468mW. This thermal profile supports reliable operation in sealed enclosures or high-density PCBs where airflow is limited - consistent with its qualification for industrial and military applications.
How does charge injection affect system performance when using the MAX4544EUT+TG035?
With 5pC max charge injection, the MAX4544EUT+TG035 minimizes voltage glitches at the COM node during switching - especially critical in sample-and-hold circuits and multiplexed ADC front-ends. For a 1nF hold capacitor, this results in ≤5mV step error, enabling sub-12-bit accuracy without additional settling compensation. This value is tested and guaranteed across temperature and supply voltage.
